How can I force a system shutdown with systemctl hibernate

#1

my inxi dump is below. the system does not shutdown (cpu is alive and fan spinning) when I issue

sudo systemctl hibernate

are there any logs that would show what is going on? I think this may be a conflict between desktop managers.
Thanks everybody.

https://www.cyberciti.biz/faq/linux-command-to-suspend-hibernate-laptop-netbook-pc/
see option 2

maybe you need the command pm-hibernate

#3

pm-hibernate does the same thing: I get a black screen and the CPU and fan does not stop. Do you know what to look for in the logs?

#4

How about using systemctl suspend?

#5

This might be of some use for insight and troubleshooting:

It's also important to note that hibernation in Ubuntu is disabled because there are issues with it on some computers, so it might not work for everyone

#6

@stephenbbb you can shutdown a system with sudo poweroff but I guess you don't want to do that. You want your system to hibernate and later wake up.

My suggestion is 1) send a message to syslog that you're going to sleep (logger "Zzzz ... going to sleep now ..."), 2) open syslog (tail -f /var/log/syslog) and look at the messages.

#7

this is the direction I want to go. please, provide more detail. do I send the message and then try to hibernate? or you just want to check if logging works? is there a brief reference to working with the logs?

#8

You could use WOL (wake-on-LAN). You need to enable this in the system's BIOS (in the network settings), then you send a magic packet to wake up the system. It works in a LAN env. To wake up your system from across the Globe is far more complicated. This article may help.

#9

I can get the log from trying pm-hibernate.
are there people who can debug that? it is quite long.
sudo poweroff works and shuts down, but hibernate goes into black screen without ever shutting down.
I am ready to post the log if there are volunteers.

#10

Muchachos,
I have some bad news to report here. The code for hibernation is not being developed/debugged any more. there was a pm-utils developer group, but the last posts in the newsgroup are from 2017. I found threads with same complaint like mine that did not get resolved. Looks like the Linux kernel can hibernate on some hardware, but not on many. So, I am unlucky with that laptop.

#11

i use this to get hibernation to work:

#!/bin/bash

if [[ $UID != 0 ]]; then
echo "Only tested on Ubuntu MATE 21.10"
echo "Please run this script with sudo or root privileges to enable hibernate"
echo "sudo $0 $*"
exit 1
else

echo "Enable hibernate on system, calculate swap file size"

#Change this value to size the swapfile X times your ram
SWAP_FILE_FACTOR=1.3

#Compute ideal size of swap ( Mem size * 1.5 )
SWAP_FILE_SIZE=$(echo "$(cat /proc/meminfo | grep MemTotal | grep -oh '[0-9]*') * $SWAP_FILE_FACTOR" | bc -l | awk '{print int($1)}')
echo "SWAP_FILE_SIZE will be $SWAP_FILE_SIZE bytes"
echo "Creating new swapfile, please wait, this may take a few minutes."
swapoff /swapfile
dd if=/dev/zero of=/swapfile bs="$SWAP_FILE_SIZE" count=1024 conv=notrunc
mkswap /swapfile
swapon /swapfile

# Get UUID & swap_offset

ROOT_UUID=$(findmnt -no SOURCE,UUID -T /swapfile |cut -d\  -f 2)

echo ROOT_UUID = "$ROOT_UUID"

SWAP_FILE_OFFSET=$(filefrag -v /swapfile | awk '{print $4}' | head -4 | tail -1 | cut -d'.' -f1)

echo SWAP_FILE_OFFSET = "$SWAP_FILE_OFFSET"

echo "Modify initramfs"

echo "RESUME=UUID=$ROOT_UUID resume_offset=$SWAP_FILE_OFFSET" | tee /etc/initramfs-tools/conf.d/resume

echo "Update initramfs"

update-initramfs -k all -u

echo "Update Grub config"
#TODO Test if grub was already containing the string
#if [[ grep -q "resume" ]]

sed -i '/^GRUB_CMDLINE_LINUX_DEFAULT=/ s|"\(.*\)"|"\1 '"${GRUB_STRING}"'"|' /etc/default/grub

update-grub
